exclamation While every effort has been made to ensure the accuracy of the fitment information listed above, it is ultimately the responsibility of the installing mechanic to perform a side-by-side comparison of the replacement part with the original to verify proper fit before installation. RF Engine is not liable for labor or consequential damages resulting from incorrect application.
